This invention relates to a novel and improved device for oiling chains, particularly of the wide flat type,vthe novel features of which will be best understood from'the'following description and the annexed drawings, in which: l

Fig. 1 is a perspective view of the invention as used with a chain.

Fig. 2 is a plan view of the device showing a fragment of the chain.

Fig. 3 is a section on the line 3-3 of Fig. 2.

Various devices have been tried for uniformly lubricating a chain of the type indicated in Fig. l, which is relatively wide and fiat. For example, it has been attempted to properly lubricate a chain of this type by means of a pipe extending transversely of the chain, and having a. plurality of holes therein through which the oil may drop uponvdifferent parts ofthe chain. This arrangement, however, has not been satisfactory, because of unequal distribution of the oil, the oilV as `it flows through the pipe naturally tending to drop or flow through the first hole to which it comes. Other devices have been found defective or uneconomical, and itis the object of my invention to provide a device which is not only capable of properly and efficiently lubricating a chain, but whichV may also be easily manufactured and applied to existing structures.

In Fig. l, I have indicated a sprocket l adapted to mesh with teeth of a chain 2, which may be of the type known as silent, this chain, for example, being composed of a plurality of links, one of which is indicated at 3. The exact details of the chain itself are not a necessary part of this invention and have consequently been omitted.`

Inthe form shown, the chain runs through a casing 4 and to one of the side walls of this casing I secure an oil box 5, here shown as having a cover 6 hinged thereto, andas being divided into a plurality of compartments by means of transversely extending partitions 7, by means of which a series of compartments is provided extending lengthwise of the chain and spaced apart in this direction.

Projecting from the box is a plurality of spouts indicated at 8V, 9, 10 and l1. VThese spouts are preferably spaced apart equal distanceslengthwise of 'the'chaim Iand are of different lengths, so that their ends'formv a.

substantially straight line.- It is'also preferable that each spout be the compartments.

In operation, oilwill be' placed in each of the compartments of the box and preferably,

connected to one of a porous substance 112 isalsofplaced the bottom of each box in such a way as to cover the inner end of the spout connected to that compartment. This lporous material" may conveniently be cotton waste, and its use is to cause the oil in the compartment to fio'w slow7 ly through thev spout connected to that compartment, so that the oil will drop or flow slowly from the end of thev spout ontotthe chain beneath it. By spacing the spout'sas shown, and byA providing spouts ofdiffrent lengths,the oil not only willdrop onto dif= ferent parts of the chain but will also be deposited substantially `uniformly across the ping from their ends will strike different portions-of the chain.

at one side thereof, a plurality of spouts projecting from said box and spaced apart lengthwise of the chain with the end of each` spout disposed over the chain, said spouts be-` ing of different lengths, whereby oil dropping from their ends will strike different portions of the chain, and a porous substance 65.

in said box covering the inner ends of the spouts, for the purpose set forth.
